Design and Experimental Measurement of Input and Output Couplers for a 6-18-GHz High-Power Helix Traveling Wave Tube Amplifier

In this article, two types of compact and effective input and output couplers for a 6-18 GHz 5-kW-level helix traveling wave tube (TWT) are designed, fabricated, and cold- tested. The input coupler section includes an impedance transformer, a conical coaxial window, and a transition to a subminiatur...
